Readers ask: How To Properly Vent A Gas Hot Water Heater?

The venting must be vertical or upward sloping so that the hot exhaust rises up through the venting to exit your home. Making sure that your home has a properly working vent system is imperative when installing a standard atmospheric vent with your water heater.

Can a gas hot water heater be vented horizontally?

All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion. Direct vent or horizontally vented water heaters are designed for installation where vertical chimneys or flues are not available or would be more expensive to install.

How much ventilation does a gas water heater need?

The amount of air required for a water heater depends on the amount of energy the water heater uses. As a general rule, water heaters need 50 cubic feet of air per 1,000 BTUs/hr.

Does a gas water heater need to be vented through the roof?

Can you vent a gas hot water heater with PVC?

As Jason mentioned, plastic (PVC or ABS) is ok to use as a venting material on powervented hot water heaters. They work by sending a huge amount of air in with the flue gases that it decreases the temperature of the exhaust going through the vent enough that it will not comprimise the vent.

What is the difference between a direct vent and power vent water heater?

The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent. A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe.

Can you vent a gas water heater and furnace together?

Many homes are built with the water heater and furnace sharing the same combustion-gases exhaust vent. This practice is common with standard efficiency (80%) furnaces. When installed correctly, this venting arrangement works with an 80% gas furnace (or lower than 80%) + gas water heater.

Can a gas water heater be enclosed?

Hot water heaters — both gas and electric — can be enclosed. However, insulation blankets are no longer recommended for hot water heaters. Most defer to manufacturer recommendations when it comes to space allowance for an enclosed water heater.

Can you get carbon monoxide poisoning from a gas water heater?

Home furnaces and water heaters are a major source of carbon monoxide poisoning, usually from poorly vented fuel sources or leaking vent pipes. Ideally, you should have your furnace and water heater inspected by a professional at least once a year.

Is a power vent water heater worth it?

Since a power vent water heater eliminates the potential for backdraft, they greatly lower the risk of carbon monoxide poisoning, although it is not totally eliminated. Energy savings is another benefit. Power vent water heaters are more energy efficient, so they require less gas to operate.

Why do I need a power vent on my gas water heater?

The main benefit of a power vent water heater is the ability to locate the water heater away from a chimney. If there is no chimney available, horizontally venting the water heater to the outside through inexpensive venting pipe instead will also benefit the homeowner by saving money.
